Brian Leathem commented on RF-12270:
------------------------------------
To force loading of the packed resources, simply include a non-visible element
on the page. It's a hack, hence why this issue is still unresolved.
> Allow RichFaces to bring new CSS/JS resources into the page after AJAX request
> ------------------------------------------------------------------------------
>
> Key: RF-12270
> URL: https://issues.jboss.org/browse/RF-12270
> Project: RichFaces
> Issue Type: Feature Request
> Security Level: Public(Everyone can see)
> Components: core, resource handling
> Affects Versions: 4.2.2.Final
> Reporter: Tomasz Kurpios
> Fix For: 5-Tracking
>
> Original Estimate: 2 days
> Remaining Estimate: 2 days
>
> Quoting the extract from official documentation (3.5 Restrictions):
> ??JSF 2 does not allow resources such as JavaScript or Cascading Style Sheets
> (CSS) to be added if the element requiring the resource is not initially
> present in the JSF tree. As such, components added to the tree via Ajax must
> have any required resources already loaded. In RichFaces, any components
> added to the JSF tree should have components with corresponding resources
> included on the main page initially. To facilitate this, components can use
> the rendered="false" setting to not be rendered on the page.??
>
> Setting rendered="false" is OK when components are in the tree. However, if
> there are lots of components on a single view, for performance reasons some
> parts might be excluded by means of <c:if> or <c:choose> tags.
> That's at least what could be done in 3.3.3. It worked fine back then.
> However, the JSF2 AJAX mechanism does not support this feature. This makes
> usage of aforementioned tags impossible in some cases.
